Description
Technical field
The present invention relates to a kind of apparatus and method of giving interior heat engine super charge by turbosupercharger.
Background technique
Turbosupercharger effect changes with engine speed speed, lower than certain rotating speed turbine, just there is no pressurized effect.When engine speed is high, turbine produces pressure over engine charge optimum pressure district, also wants outside pressure release.
The high-temp waste gas that acting turbine is got rid of is a kind of wasting energy.
Air filtering core device is negative pressure work before turbosupercharger, affects intake efficiency.
Summary of the invention
Therefore the method that the present invention overcomes the above problems is turbosupercharging air inlet system and effective ways.Do not increase energy consumption, can also increase engine power method.
The present invention is divided into mechanical turbine supercharging and direct turbosupercharging air inlet method and device, and wherein mechanical turbine super charge method and apparatus can be realized dynamic feedbacks.Mechanical turbine boosting method and device than the direct air inlet of turbine many speed changer being connected with motor.Apparatus of the present invention comprise speed changer 2., turbine 3., bleeder mechanism 5., air cooling filter 6., heat exchanger 9..
Flow process of the present invention is: 3. 2. motor 1. bent axle connect turbosupercharger by speed changer, when bent axle low speed, also can provide the rotating speed that turbine is higher, turbine not through filtered air pressurization by pipeline arrive bleeder mechanism 5. in, 5. bleeder mechanism is divided into two-way pressurized air: 6. the pipeline of leading up to connects air-strainer, in filter cleaner, there is cooling pipe, the thermal absorption that turbosupercharging is produced is got rid of, and through filtration and cooling fresh air, by inlet valve port pipeline, 7. enters motor 1..9. 8. the pipeline of separately leading up to connect heat exchanger, after the high temperature that absorption turbine scavenges, by pipeline, 10. enters cylinder exhaust pipe
during high engine speeds, amount of heat is required diligent over air inlet turbine by exhaust gas turbine generation, and 2. unnecessary merit feeds back to bent axle by speed changer, increases engine power.
During design philosophy of the present invention, motor secondary speed when rotating speed is low is also low, and air amount amount is few.In order to make motor more early reach suction pressure, under rotating speed one stable condition, can only strengthen turbine size.Large turbine produces and can surpass the best suction pressure of motor needs when high speed, use bleeder mechanism head it off, unnecessary air pressure is assigned to an other road and reduce phlegm and internal heat in the pipeline of exchanger.Go engine booster air to pass through air cooling filter (resembling vacuum cleaner washable), cooling and clean pressurized air enters motor.Like this can engine intake pressure stability, guarantee motor more stable work.An other road pressurized air absorbs by heat exchanger the heat that motor is got rid of, and through the pressurized air heating, enters near inblock cylinder valve, and effect is to blow out near the waste gas of relief opening.After mixing with waste gas, enter exhaust gas turbine acting, during high engine speeds, amount of heat is required diligent over air inlet turbine by exhaust gas turbine generation, and unnecessary merit feeds back to bent axle by speed changer, increases engine power.
Key device of the present invention be bleeder mechanism 5..Bleeder mechanism working principle is: near measuring cylinder, pressure is controlled the electric valve that voltage divider removes filter cleaner pipeline, near the pressure of cylinder is little, valve is just opened greatly, large, the valve of pressure is just opened littlely near cylinder, as the turbine mouth throttle down immediately of intaking.Another road electric valve of going of exchange that reduces phlegm and internal heat, near cylinder, little, the valve of pressure is just opened littlely, and near cylinder, large, the valve of pressure is just opened greatly, as the turbine mouth throttle down immediately of intaking.So just can stablize near the pressure of cylinder suction port, for motor stable operation is by better condition.3. the scavenge turbosupercharger that is mixed of the air of supercharging heat absorption and cylinder does work.
6. air cooling filter of the present invention can be placed on before turbosupercharger, best is be placed on bleeder mechanism 5. after.Existing Main Analysis air cooling filter is placed on the situation after bleeder mechanism.Pressurized air arrives filter cleaner after by bleeder mechanism, and this is a kind ofly under pressure, to filter, and can reduce filter volume.Filter cleaner way resembles detachable cleaning dust remover filter collection ash bucket, should be that sealing is gastight certainly.Filter has sniffer, and reflection grieshoch is how many and will clear up situation.Pressurized air water cooling exchanger after filtering, the absorption of heating that supercharging is produced.Filtrating equipment and water cooling exchanger integrate, and can save space.
Heat exchanger of the present invention is that high-temp waste gas and the next pressurized air of bleeder mechanism that exhaust gas turbine is got rid of carry out heat exchange, make pressurized air absorb the partial heat energy in high-temp waste gas, and engine exhaust mixing relief exhaust gas turbine produces more high-power.
The present invention is applicable to gasoline and diesel engine, can allow engine turbine get the hang of ahead of time, has better acceleration performance.
